sAP-ExTRAcToR.

Patented Jan. 8, 1907.

Application filed October 16, 1906. Serial No. 339.264.

To all whom it may concern:

Be it known that I, VINoEN P. MoVoY, of

Pensacola, in the county of Escambia and State of Florida, have invented certain new and useful Improvements in Sap-Extractors and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

In an application for Letters Patent of the United States, Serial No. 332,526, filed by me August 29, 1906, I disclosed a sap-collector comprising a spout having at its inner end a circular flange for fitting tight against the edge of a bore in a tree, sealing such bore so as to permit of the creation of vacuum therein, the sap-receptacle being detachably secured to the outer end of the spout.

The primary object of my present invention is to so form the flange that it may effectively seal a bore of even less diameter than that of the flange.

A further object is to avoid interfering with the free flow of the sap.

The invention will be hereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view showing a portion of a tree with the sap-receptacle detached. Fig. 2 is an outer face view of the spout. Fig. 3 is an inner face view thereof.

As pointed out in my before-noted application for patent, the spout 1, which is of elbow form, is provided at its upper end with a large circular flange 2, from the axial center of which, above the upper end of the spout, projects a post 3, threaded to engage a subbore formed centrally of the main bore 4 cut in a tree, which main bore is designed to be sealed by the flange, so as to enable the sap to be extracted under the presence of a vacuum.

According to my present improvement it is not necessary that the diameter of bore 4 and that of the flange 2 should be uniform. In the resent instance the flange is formed on its fl at face with a circumferential knifeedge rib 5, which will form a bearing against the tree without binding or stopping u any of the pores thereof, such rib being rawn tight against the tree as the post is screwed home.

The advantages of-my present improvement are apparent. It is manifest that the bores in the tree may be of any desired size within the range of the diameter of the sealing-flange and still be securely sealed by the latter. At the same time I avoid interfering with the free flowof the sap.

The other features shown in the drawings being fully described in my above-noted application for patent specific reference thereto in this case is not necessary.

I claim as my invention A sap-collector comprising a spout having at its upper end a flange, a circumferential rib on the inner face of such flange formed With a knife-edge, a threaded post extending from the flange for engaging the tree and holding such knife-edge tight against the face of the latter around a bore therein, and an air-tight receptacle detachably fitted to the lower end of said spout.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
